JAMES R. MOWANE, OF BIRMINGHAM, ALABAMA.

SHAKE-OUT BOX.

Be it known that I, JAMES R.- MOVVANE,

a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented a new and useful Shake-Out Box, of which the following is a specification. The invention relates to a shake-out box constituting an element of the pipe making apparatus, covered by my (Jo-pending application, Serial No. 507 ,127 filed July 12, 1909, but not specifically claimed therein.

The object of the present invention is to provide for pipe pits a shake-out box, adapted to permit the flasks to be shaken out at a common point, and capable ofenabling the molding sand to be returned to the ramming platform at intervals in comparatively small quantities, whereby the sand may be accurately retempered and immediately used.

Another object of the invention is to pro. vide' a shake-out box of this character, adapted to afford a support for the flasks,

I while the pipes are being pulled, and capable of being readilyhandled by the crane of a pipe pit, and of enabling its contents to be'easily dumped when it arrives at the de sired point.

With these and other objects in view, the

invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion,

size and minor details of construction,

within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. a

bottom sections 6 above the bottom of the pit, or other supporting surface upon which the shake-out box rests. The legs 5', which may be of any suitable construction, preferably consist of angle bars, extending from the top to the bottom of the receptacle, and 7 7 fitted in the corners or angles formed by the ends 3 and the projecting terminal portions or flanges 4 of the sides 2, and they are riv-.

eted,-or otherwise secured to the same. The

bottom sections 6 are connectedat their outer longitudinal edges to the lower edges of the sides 2 by hinges 7, and they are adapted to swing downward to dumpthe contents of the shake-out box. The sections 6 of the dumping bottom are connected by the inner edges thereof. The shaft 9, which is adapted to be rotated to open and close the dumping bottom, is equipped at one'end with a hand wheel 11, or other suitable means for rotating it, and it has a ratchet wheel 12 fixed to it and engaged by a pivoted pawl 13, mounted on the outer'face of the adjacent end 3 of the box or receptacle, and adapted to lock the shaft against retrograde rotation to secure 'the hinged sections 7 of the bottom in their closed position. V

The shake-out .box is reinforced at its upper edges by angle bars 14:, forming inwardly extending horizontal flanges 15, upon which are mounted inner and outer brackets 16 and 17 for supporting central and side flask-receiving bars 18 and 19. The inner brackets 16, which are arsupporting rangedin pairs at the center and ends of the box or receptacle 1, are approximately U.- shaped consisting of ahorizontal bottom 'attaching portion 20, and inner and outer verticalarms. The outer brackets 17 aresub: stantially L -shaped and consist of horizontal attaching portions and upwardly extending arms. The adjacent arms of the supporting brackets are spaced apart to receive the horizontal bars 18 and 19, which are arrangededgewise with relation to the flasks.

The centrally arranged U-shaped and L- shaped brackets are mounted upon a top cross bar 21, preferably T-shaped in cross section and suitably connected at 'itstermlnals 0 the sides of the box or receptacle and supported by metallic bars or cleats 22, lo-

cated at the inner faces of the sides 2 of the box or receptacle and preferably T-shaped as shown, but the top cross bar 21 and the vertical bars or cleats 22 may be constructed of any other suitable material.

The spaced horizontal bars 18 and 19 form in conjunction an open grated frame, which is supported above the top of the box and constitutes a superimposed seat for the flasks, the lower portion 23 of one of which is illustrated in dotted lines in Fig. 3 of the draw ing. The flask-supporting frame is equipped atopposite sides with inclined wings 2st, forming guards and adapted to center the flasks with relation to the shake-outbox, so that the sand will fall into the receptacle when the pipes are pulled. The guards or wings, which diverge upwardly, are composed of upwardly extending bars 25 and longitudinal connecting bars 26, secured to the upper ends of the bars 25. The bars 25 have their lower portions riveted, or otherwise secured to the outer faces of the vertical portions of the brackets 17, and the upper portions of the bars 25 are bent at an angle and extend upwardly and outwardly from the lower vertical attaching portions. The longitudinal connecting bars 26 are set in angular bends or seats 27 of the upper ends of the bars 25, and have their side faces arranged at an inclination. In placing a flask upon the shake-out box, the upwardly inclined guards or wings operate to center the same, so that when a flask rests upon the shake-out box, it will occupy a position directly over the receptacle, whereby all of the molding sand will fall within the box or re cept-acle 1. The box or receptacle 1 is constructed of a length to receive a flask at either side of its center, but it may be made of any capacity, as will be clearly apparent, and the superimposed flask-receiving seat or support may be varied in construction to adapt it to the character of the flasks and to secure the desired strength.

The shake-out box is equipped at its ends with upwardly extending loops or bails 28, adapted to be connected with the crane of a pipe pit, when it is desired to dump the shake-out box. The loops or bails, which are tapered upwardly, are composed of two sides and a connecting top portion, and the lower terminals of the sides are rigidly attached to the outer facesof the ends of the receptacle. The shake-out box, which is portable, enables the flasks of an entire pit or section of a pit to be shaken out at a common point, and the handling of the sand from the shake-out box enables the sand to be tempered immediately in small quantities with an accurate amount of clay wash and new sand, and the successive use of the sand will permit a pipe pit to be operated with a comparatively small amount of sand.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
